Does Rectangle.getX() return the upper corner or the center?

Question

Say I have a java.awt.Rectangle set up as:

x - - - - - - -
| - - - - - - - |
| - - - - - - - |
| - - - - - - - |
| - - - y - - - |
| - - - - - - - |
| - - - - - - - |
- - - - - - - - -

Does getX() return the x-coordinate of x or y?

Answer 1

getX() returns the top-left x-coordinate.

The source says it all:

Looking at the Rectangle(x, y, width, height) constructor:

public Rectangle(int x, int y, int width, int height) {
   this.x = x;
   ...
}

The docs for the above says:

Constructs a new Rectangle whose upper-left corner is specified as (x,y)

Looking at getX():

public double getX() {
   return x;
}
